Overview

• Detailed description of Cost Matrices– Commuter– Transportation– Accessibility

• Steps to building a simulation and understanding your results

Commuter Cost Matrix

• Captures changes to time per trip for off-the-clock, work-related trips.

• Calculated through VHT/Trips

• Think—Would NYC still be a financial center without its subway system?

Transportation Cost Matrix

• Captures the on-the-clock business travel and transport of goods.

• Calculated in two ways:– Ratio of VMT to VHT

between alternate and baseline scenarios

– Cost per trip of commercial truck deliveries

Accessibility Cost Matrix

• Calculates changes in access to intermediate inputs and consumer goods

• Explains residual bias toward local suppliers

• Calculated through Trips/VHT

Accessibility Cost Matrix

Baseline value calculated with REMI dynamic estimation to estimate distance deterrence factors which are normalized to 1.

Capturing Mobility Benefits of Long-Range Plans (1)

• Step 1-Importing Travel Files– “maintenance

only” base case– “maintenance +

capacity improvement” alternate case

Capturing Mobility Benefits of Long-Range Plans (2)

• Step 2-Identifying Adjustments to Simulation Options– Emissions– Safety– Operating Costs– Value of Time– Cost Matrices

Capturing Mobility Benefits of Long-Range Plans (3)

• Step 3- Understanding the Results– Analytical graphs– Labor productivity?– Sector sensitivity to

transportation?– Industrial

composition?– Cross-regional

benefits?
